自动信任协商中信任证存储策略研究

Research on Credential Storage Strategy in Automated Trust Negotiation

分布式信任证存储策略存在单点失效及容错性差等问题,可能导致信任证丢失。为此,提出一种改进的分布式存储策略。该策略以分布式存储策略为基础,运用已有的数据结构支持信任证存储策略的设计。基于资源冗余的思想,采用多信任证副本和信任证恢复机制,提升系统容错能力。实验结果表明,该存储策略具有较好存储均衡性。

Aiming at the problem of single-point failure which may lead to loss of credentials and poor fault-tolerance in distributed storage strategies, an improved distributed storage strategy is proposed. Using distributed storage strategies as a basis, exiting data structures is used to support the design of the credential storage strategy. Based on the idea of resource redundancy, multiple credential copies and credential recovery mechanism are employed. Experimental results show the storage strategy has increased fault-tolerance and balanced storage.
